October marks the beginning of the SAD season.
Seasonal affective disorder (SAD) is a type of depression triggered by shorter days and reduced light. So far this month, Loyola University Medical Center psychiatrist Dr. Angelos Halaris already has treated several patients for the disorder.
“We are in the midst of the full-blown SAD season,” Halaris said.
Seasonal Affective Disorder affects between 3 percent and 5 percent of the population, depending on what part of the hemisphere the study has been conducted. SAD is thought to be related to a chemical imbalance in the brain, brought on by lack of light due to shorter days and overcast skies.
SAD causes depression, excessive sleepiness, lack of interest and motivation and fatigue, making it difficult to get up in the morning. In the most severe cases, people can stay in bed all day, or even attempt suicide. The season lasts until mid-April.
“Seasonal affective disorder should not be taken lightly,” Halaris said.
